How to connect to Pradox v4 through Java

I am trying to make a connection through my Java program to Paradox v4.x and have dowloaded the JDBC Drivers. Can someone pleae tell me or have a sample on how to connect to Paradox through Java. It looks like there are some samples in Paradox_JDBC30demo.zip but I don't find Paradox_JDBC30demo.zip anywhere. Where can I download this zip file or if someone have a small sample to connect would greatly help.
